We could start a lengthy discussion on how quickly a breaker should open. Given that rarely, if ever, will the short (as opposed to the surge from a spark) go through the loco's electronics, how fast is fast enough? As I noted above, the PH-180 breaker is so fast that it can be a great pain in the wantaffle if you have, as I do, a large stable of rolling stock as much as 80 years old, with varying flange separation.
